8P/Tuttle, elements of physical protection for the body and its movement

8P Tuttle is an amor comet discovered in January of 1858. There ia a prediscovery image back to January of 1790. It reached the perihelion in January of 2008.

The orbit is between the Earth-Moon system and Saturn. It has a perihelion of 1.02 AU and an aphelion of 10.38 AU. The semimajor axis is at 5.70 AU. It has an orbital period of 13 years and 233 days. It has an inclination of  54.9º (vigintile 54º [=biquintile 144º > 0º Capricorn], 0º55' orb). It has  a diameter of about 4.5 km.


Radar observations in January 2008, revealed that your kernel is actually made up of two cores in touch.

8P/Tuttle is the comet that generates the meteor shower known as Ursids, from day 17 to 26 December of each year. Its name is due to the fact that its radiant point is located very close to the star Kochab (Beta Ursae Minoris) in the constellation of Ursa Minor.

Orbital resonance:
13:6 with Saturn (99.6%)
13:15 with Jupiter (99.6%)
-
4:15 with Vesta (99.7%)
2:5 with Europa (99.8%)
7:15 with Cybele (99.7%)

  
8P/Tuttle is related to elements of physical protection (Saturn) for the body and its motion (Earth-Moon system), such as for example the fireman's uniform with thermal insulators, helmet, sunglasses, shield, etc.
